Question

Consider the following 2009 4WD, 6-Cyl SUV data.
a. What value do you anticipate for a correlation coefficient of the two variables annual petroleum consumption in barrels, x, and annual tons of CO2 emitted, y? Explain.
b. Calculate the linear correlation coefficient for the two variables annual petroleum consumption in barrels, x, and annual tons of CO2 emitted, y.
c. Is the value found in part b approximately what you anticipated in part a? Explain why or why not.
d. Does it make sense for the data to demonstrate such a high correlation? If the amount of consumption doubles, what do you think will happen to the tons of CO2 emitted? Be specific in your explanation.
